Seeking paper tape punch

[Mike Stein]

If anybody actually wants to build one I have the important part, motor
driven with solenoid operated cam driven punches; would only need a
suitable interface and maybe a cabinet.

Don't know if it would be worth while with today's shipping costs though,
unless you're local in the Toronto area.
